OK, so if I have 4 ni-mh P511's for my canon drebel and 12 ni-mh AA batteries for my flash (4 AAs are used at a time) and board a plane for a trip to a car show will I be bequired to throw them away?

Other wise, I'll jsut send my batteries to the hotel where I am staying and this will avoid the situation at the airport.

Anyone else???

It's for Li-Ion batteries which were catching fire or explode lately in laptops and cellphones plus lots of recalls from manufacturers. Ni-MH batteries should be ok. Your DRebel uses Li-Ion rechargeables. You should keep the plastic protective cover on the spare battery.
